How this calculator works
The answer does not change between Quick and Detailed. This is the professional finance underneath it — the formula, assumptions and mechanics you can inspect when you want the extra detail.
Contribution per physical unit
Single-unit contribution = single selling price − unit cost. Bundle contribution per physical unit = bundle selling price ÷ bundle size − unit cost.
Mix weighting
The blend is weighted by the share of physical units sold through bundles, not by the share of transactions that are bundle orders.
